The 151-point Elo gap (1790 vs 1639) is the single largest signal in this match, built from a long track record of 340 matches for Mejia at this level. That gap alone explains most of the model's 71% probability for him.
Recent form reinforces the rating gap rather than contradicting it. Both players are 6-4 in their last 10, but Mejia's wins include victories over players rated 1911 and 1905 — well above his own baseline — while Rodriguez Taverna's recent wins carry no such quality. This suggests Mejia's level has been tested and held up, which matters more than the identical win-loss record.
At Bogota's 2640m altitude, thinner air speeds up the ball and typically rewards the better server, since return timing becomes harder. Mejia's 64% serve-points-won is a shade above the opponent's 62%, so the altitude effect leans slightly in his favor, though the gap is not large enough to be decisive on its own.
Return numbers are almost a mirror image (39% for Mejia vs 41% for Rodriguez Taverna), meaning neither player has a clear edge breaking serve. The more meaningful asymmetry is physical: Mejia has played 5 matches in the last 14 days on just 1 day of rest, compared to only 2 matches and 2 days of rest for his opponent. Over a Challenger-level match, that workload difference could show up as a drop in movement or serve consistency for Mejia as the match progresses.
The two players have met once, with Rodriguez Taverna winning that match. It's a real data point but a single meeting isn't enough to override the much larger and more established Elo gap; the model treats it as a minor factor.
Even with the model favoring Mejia at 71%, the market prices him higher at 75% (odds of 1.34), producing a -5.5% expected value. In practice this means betting Mejia here is paying a premium above what the model thinks he's worth — the market is not obviously wrong, and Elo-based estimates on Challenger markets are inherently soft and unproven live. Being the favorite here is not the same as being a value bet; on these numbers, there isn't one.
